Getting fair value for your time, IP and future value of the business. And ensuring there is no non-compete clause unless she pays a premium for the privilege. You may also want to retain ownership of the web site code so you can re-use it in another business venture.

I'm not a lawyer, just someone with life experience and a little bit of legal knowledge. Not enough knowledge to be certain, but enough to be useful in some situations, and dangerous in others

The business is financed by by personal finances until such time the site starts making money.

I don't want to be in the business anymore anyway. I want out. I don't care about a fair value for my time or IP.

The biggest problem I have is that the website is not finished. It is in its basic form only and there is a lot more to do. I need an indemnity of some kind absolving me of both any website features not yet installed and any changes a future developer makes that impacts my code unexpectedly. My partner has really lost interest in the business and has not checked the website for the last few months. Is an indemnity appropriate, and if so, what is it called?

Thanks again for the advice. Because the numbers are not huge here, and that fact that the website code is portable and can be easily re-used, it is more simple to get out now. I'm glad that this happened now, and not two years down the track when the business may be making making actual cash, and I'm asked to hand over part of my ownership for her new beau!
